var forest={};

?Object.defineProperties(forest,{

? title:{value:'fe',enumerable:true},

? corp:{value:'BABA',enumerable:true},

? salary:{value:'50000',enumerable:true,writable:true},

? luck:{

? get:function(){

? return Math.random()>0.5?'good':'bad';

? }

? },

? promote:{

? set:function(level){

? this.salary*=1+level*0.1;

? }

? }

?});

?forest.salary;

這個代碼在Sublime怎么執行？

而且會報錯

Uncaught TypeError: forest.promote is not a function
